'''''Isopodichnus''''' is an [ichnogenus](/source/Ichnotaxon) of [trace fossil](/source/trace_fossil). Ribbon-like in form, ''Isopodichnus'' traces were likely formed by the activity of an [isopod](/source/isopod) [crustacean](/source/crustacean) foraging within the preserved sediment. Parallel to the bedding plane, a central furrow is flanked by two hypichnial ridges. Trails may also exhibit scratch marks and be associated with ''[Rusophycus](/source/Rusophycus)''-like resting traces. ''Isopodichnus'' are very similar in form to ''[Cruziana](/source/Cruziana)'' traces, making delineation of the two forms difficult, and controversial.<ref>Richard G.
